I've done a search on this and i haven't been able to come up with an answer for my particular situation....

Ok: All of my needles light up fine...except for the temp needle....but last night it was raining and it began blinking off and on....is this something that normally happens on our models/years? any info on this? thank you

 

Yep, it'll be going out soon! You can try prolonging it a little longer by turning the illumination down to it's lowest setting, as most of us already do. Plan on replacing it or doing the lextech upgrade.
